Is it normal to always smile?
There is this girl that went to my last high school that never stopped smiling (well she did have a straight face ONCE but it was brief). I mean even if she's lost in thought she's smiling. While she speaks she's smiling. She probably smiles through constipation!
But seriously, is that normal? Do you think she's a really happy person, or maybe if her face is just like that? It's a genuine smile too.
